MILK BOTTLE CAP Filed OC. 17. 1928 Patented Feb. 4.,.-1930 l UNITED STATES PATENT oFFlcE .uurs n BUDD, or BATTLE GROUND, WASHINGTON, iissIofNonI 'To M. a M. sALEs a MFG. oo. INo., or PORTLAND, onEGoN MILK-BOTTLE CAI' Application filed 0ctober'17, 1928. Serial No. 313,193.

-it will prevent milk from running down the side of the bottle, whichv is obviously lindesirable.

These, and other objects, will become more apparent fromV the specification following as illustrated in the laccompanying drawing, in which:

Figure 1 is a fragmentary view of the upper portion of the'milk bottle showing its mouth and the new closure member broken away in section and showing -the devicein a closed position. Figure 2 is similar to Figure 1, except that the bottle is beingincline-.l for pouring and that the closure member has` dental opening of the door, and is merely bent tov one side as shown in Figure 3) when it is desired to open the door.

In Figure 6 it will be noted that instead of having the beveled edges 13 and 14 that the disk 10-A consists of an upper portion 11-A and lower portion 12-A, both of which have a door opening formed therein, the only difference being that in the member 12--A the door opening is slightly smaller than in the memberl11-A which forms a shoulder limiting the closing travel of the door.

In order that the door shall remain in the position desired as best adapted for smooth pouring of the milk, there is introduced a soft Wire stay rod 20 between the members 11 and 12 and 11-A and 12-A, which holds thek door in the desired position against any springing action which may exist in the hinge 16 or lf3-A.

The operation of the device is as follows: After the bottle 21 is filled and capped by hand or by such machines as are now in common use and delivered to the consumer, and it is desired to remove a portion of the milk from the bottle it is only necessary to move been set for pouring. Figure 3 is a plan ofj the staple 19 slightly to one side, as shown the device showing its door open. Figure 4 1n Figure 3, and lift upwardly on the tab 17 isa plan ofthe device showing its door closed. CauSlng the door to Open. The door is now Figure 5 is an enlarged section taken along the line 5-`-5"in Figure 4. Figure 6 is an enlarged section through a modified form of the device in which the beveled edge door 1s -replaced by a door having a shoulder formed 10 is formed an opening having beveled edges 13 against which can rest the edges 14 of a door 15, whose hinge 16 is formed by material in the member 12 which has not been cut away. A tab 17 is fastened on the door 15 by means of a suitable staple 18, or may be formed out of the material in the door itself,

as is common practice. A wire staple 19 is placed across the side of the door frame whichl serves as a latch -to prevent acclswung back to approximately the position shown in Figure 2, and it will be found that the milk can lnow be easily and smoothly poured from the bottle without coming into contact with the rim 22, which might ordinarily be contaminated.

It it is desired to pour all of the milk out of the bottle it is only necessary'to close the ldoor 15, and if the bottle is to be subjected to rough handling it is well to move the staple 19 back to the position shown in Figure 4 to prevent any accidental opening of the door.

In many instances when the form shown in Figure 6 is employed the staple 19 will not be necessary.

It can readily be seen that the size of the door 15 and the exact shape illustrated in the drawing are immaterial, as these can be va ried greatlywithout departing from the spirit of this invention.

I am aware that milk bottle caps have long been constructed in the gast, I therefore do not wish to cover such evices broadly, but I do intend to cover allsuch forms and modifications thereof as fall fairly within 5 the appended claims.

I claim: i 1. A milk bottle cap consisting of a circularpa er disk having an opening formed throug same having a closure hinged to one side of said opening, the sides adjacent to said hinge being perpendicular thereto, the remaining side consisting Aof two straight faces angling outwardly toward the middle of the closure, and a soft wire stay Within the structure of said door. and cap perpendicular to its hinge adapted tobe bent as said closure is moved and to hold said door in the position to which it is moved.

2. A milkbottle cap consisting of a circular paper disk having an opening formed through same having a closure hinged to one side of said opening, the sides adjacent to said hinge being perpendicular thereto and the remaining side having its middle project- 'as ing beyond its ends, av staple in said disk adapted to be bent over the point of said closure and-hold same in position, a soft wirer stay Within the structure of said door and cap perpendicular to its hinge adapted to be l bent as said closure is moved and to hold said door in the position to which it is moved, and a tab attached to the pointed end of said door on its outer side adapted to facilitate the opening of said closure. 3. A closure for milk bottles consisting of a paper disk having an opening formed' therethrough, a closure for said opening hin ed to one edge thereof, a wire within sai hinge perpendicular to said hinge adapt- 40 ed to hold said closure to any open position. 4. A closure for milk bottles consisting of a paper disk having an opening formed therethrough, a closure for said opening j hin ed to one edge thereof, a wire within sai hinge per endicular to said hinge adapted to hold sai closure in any o en position, and latch means for holding said closure in a closed position. v 5. A milk bottle cap consisting of a circular paper disk having an opening formed through same having a closure hinged to one side of said opening, the sides adjacent to said hinge being perpendicular thereto and the remaining slde having two obtuse faces '55 forming a point thereon, and a sta 1e in said disk adapted to be bent over the po1nt of said closure and hold same in position.
